[x.x.x]: https://github.com/bazelbuild/rules_python/releases/tag/x.x.x

### Changed
* (rules) `py_proto_library` is deprecated in favour of the
implementation in https://github.com/protocolbuffers/protobuf. It will be
removed in the future release.
* (deps) Upgrade the `pip_install` dependencies to pick up a new version of pip.
* (toolchains) Optional toolchain dependency: `py_binary`, `py_test`, and
`py_library` now depend on the `//python:exec_tools_toolchain_type` for build

The python rules are in the protobuf repo directly, not in a python-specific repo? I thought I remember seeing a BCR PR where they were adding various proto_{java,python,etc} repos so e.g. java wasn't pulled in when only python was used.

Yes.

Hm, do you mean rules_proto_grpc_*? I imagine those support gRPC, but I wasn't part of that effort.

For workspace builds, shouldn't there be some sort of proto-setup call still? Did I miss where it is?

There's a protobuf_deps call just after. We only need to setup protobuf, now that the rules are moving there.
